1 I The present invention relates to windows and embodies, more particularly, a window structure adapted to be .utilized with an opening to provide the entire area of the opening for ventilation purposes where the window is moved to the fully opened position.

More particularly, dow structures of the sliding type,.wherein full advantage is taken, for purposes of ventilation, of all of the available area of the opening in the building structure. a

In sliding windows of the type now commonly used, certain disadvantages arise that are well known. The usual double hinge sliding window,

for example, requires counter-weights or spring balances to maintain the sashes in an open or closed position, and less than one-half of the opening in the building structure is available for purposes of ventilation. Where the sashes are sliding in a common plane, the building structure has had to be designed to receive the sashes when the latter are slid into the fully open position.

An object of the present invention isto provide a sliding window structure, the sliding elements of which move in a plane other than tha of the building structure.

A further object of the present invention is to provide a sliding window structure of the above character wherein the entire area of the opening in the building structure is made available for purposes of ventilation.

Yet another object of the invention is to provide a sliding window structure of the above character wherein the entire structure is provided as a unit and adapted to be mounted on the building structure without modification of the latter.

Another object of the invention is to provide a sliding window structure of the above character adapted to be mounted as a unit on the exterior of the building structure to make available the entire window opening in the structure for purposes of ventilation.

Further objects and advantages of the invention will appear as it is described in greater detail in connection with the accompanying drawings, wherein Figure 1 is a view in front elevation of a window constructed in accordance with the present invention, the elements thereof being shown in the closed position;

Figure 2 is a view similar to Figure 1 showing the window sashes moved into the open position;

Figure 8 is a view in vertical section taken on L line 88 of Figure 6 and looking in the direction of the arrows;

along line l|ll of Figure 6 and lcokin'g'in thl direction of the arrows.

With reference to the above drawings and particularly Figures 1-5, a. building structure 1:

shown at In as being provided with 'a windov opening, the edge of which is shown at H. Th4 interior of the building structure maybe provided with plaster l2 and a stop or other elemenl I 3, of wood or other suitable material, is provided within the window opening.

In accordance with the presentinvention, a umtary window structure is provided consisting of a metal casing I4 forming a sill l5 and top piece I6. The sill l5 extends outwardly and is downwardly flanged at I! to overhang the outer side of the building structure.

The top piece 16 also extends outwardly of the side of the building structure and is downwardly flanged at l8 to form a hood or cover member for the sash hanging mechanism to be described presently. The hood is completed by an inner plate l9 which is suitably secured to the top piece It and which serves as the supporting mechanism for the hanger. I

As shown in Figures 4 and 5, the side walls of the casing M are formed with flanges 20 and 20a to enable the casing to be sealed when the sashes are in the closed position. The flanges 20 lie in the same plane as the plate l9 while the flanges 20a lie adjacent the inner edge of the sash. This sealing structure will be described more particularly hereinafter in connection with the sash structure.

In order that. the sash may be slid from a closed to an open position, the hood I8 is provided with a telescoping hanger mechanism comprising a channel member 21 mounted on the plate l9. A U-shaped guide member 22 is secured to the channel 2| and formed with top and bottom guide tracks 23. Roller bearings 24 running in the tracks 23 support a track 25 upon which rollers 26 are adapted to run.

The sash consists of a frame 21 in which a glass plate 28 is mounted, the entire structure of the window preferably being of a suitable metal. The sash frame 21 is hung on the rollers 26 by means of a hanger 29 in which the rollers are journaled. The sash frame 21 may be secured to the hanger 29 by welding as indicated.

The details of the telescoping hanger structure are well known in the art and form no part of the present invention, this invention residing in the combination of elements forming the unitary sliding window structure herein described.

At each end of the hood IS, a reduced section a sealing cap 3| having flanges 32 in which suitable sealing material 33 is provided. The reduced section is received within. the flanges 32, as seen in Figure 4, thus effectively sealing the interior of the hood when the sash is in its closed position.

The outer vertical edge of the sash frame 21 is provided with a sealing strip 34 having a flanged reentrant portion 35 forming a grove within which a suitable sealing material 36 is received. The flange 20a is adapted to be received within the groove to engage the material 36 in the closed position of the sash frame 21, thus effectively sealing the sash to the casing at the sides of the window when the window is closed.

The bottoms of the sash frames 21 are sealed to the flange l1 by means of a strip 31 which is similar to the strip 34, the flange l1 being sealed to the strip 31 similarly to the way in which flange 20a is sealed to strip 34. Spring pressed bullet plungers 38 and 39- in the plate I! and bottom flange l1 urge the frame outwardly to maintain wiping engagement between the strips 34 and 31 and the stationary flanges on the casing at all times.

The meeting edges of the sash frames 21 are sealed by the structure shown in Figure 5. The left-hand sash frame 21 is provided with a rib 40 which engages sealing material 4| carried in a U-shaped strip 42 secured to the adjacent vertical edge of the right-hand sash frame 21. When the sash frames 21 are in a closed position, the rib 40 engages the sealing material 4| and seals the sashes together while in the position shown in Figure 5.

In the form of the invention shown in Figures 6 ,7, and 8, the window structure is such that the span of the window opening is closed by four sliding sashes instead of two, as in Figures 1-5. In this modification of the invention, the casing and manner of mounting it in the window opening is similar to that shown in Figures 1-5.

In order to accommodate the greater number of sashes, however, the hood i6 is formed with an intermediate plate 43 which is similar in structure to plate I! and supports a second hanger 44 which is similar to the hanger 29. The hanger 44 supports a second sash frame 45, similar to the sash frame 21, thus providing two sliding sashes on either side of the window, as shown I in Figures 6 and 7. The hood may be sealed in the same manner as described above in connection with Figures 1, 2 and 4, inclusive. Thus, the hanger 44 may be provided with a cap similar to the cap 3| which is adapted to cooperate with suitable flanges formed on the hood I 6 and the intermediate plate 43 to form an effective seal, as illustrated in Figure 9. A seal may be formed at the side edges of the inner and outer sashes when in a closed position by suitable cooperating flanges formed at the inner edges of the two outer sashes and at the outer edges of the two inner and the third of which lies directly below the two center sashes in this flgure;

It will be apparent that the details of the window structure, as well as of the sliding sash and related elements, may be varied considerably and various forms of sealing devices provided to seal the movable elements to one another and to the adjacent stationary elements, and the invention is not to be limited save as de- 4 flned in the appended claims.
